Doomtree co-founder, punk philosopher and lyrical bomb-thrower Stefon Alexander, aka P.O.S, makes tight, declamatory music that builds on the Minneapolis-bred rapper and producer’s penchant for grinding beats and radical lyrics. Known for welding hip-hop with guitar squalls, screamed vocals, and futuristic beats fit for a Berlin nightclub. New album Chill, dummy out 1/27/17 on Doomtree Records.
